This year organisers say they are taking safety issues very seriously.

Mr Hanson says a number of changes have been made to the beach set-up.

"We've brought a lot of those age group areas together so they're not so spread out and there's a lot of extra space between the various areas - between the boats and the skis, and the boards and the swimmers."

"So I think that's certainly a key message or a first step towards really ensuring that we're taking all of this safety situation very, very seriously indeed."
